Industrial Wastewater JS: 202/1991

 Domain

This regular Jordanian specification is concerned with stipulations and qualities that must be a available in industrial waste water which might be disposed to the surface water or water that naturally feed ground water or that can be reused for irrigation purposes.

Definition

Industrial wastewater :Water outgoing or resulting from using water in some or all stages of manufacturing , cleaning , or cooling or any others whether treated or not .

General Stipulations
The following general stipulations must be provided :

  • Industrial wastewater shall not negatively affect the public environment in order to protect the health and safety of man and shall not also affect the social and economic development in the area or the basin that might be impacted by this pollution.
  • The final use of the industrial wastewater shall determine the properties or instructions that must be applied on the quality of water indicated in table No.1 provided that the environmental balance in that area shall not be disturbed .
  • It shall not negatively affect the quality of ground water in the area of industrial wastewater disposal or the basin impacted by that .
  • It shall not affect the quality of surface water receiving industrial wastewater and it shall not negatively affect the aquatic life . 
  • In the case of reusing industrial wastewater for any stage of manufacturing or irrigation stages , it shall not negatively affect the health and safety of the employees in the factory or product's consumers .
  • In the case of reusing industrial wastewater for the purposes of irrigation , the following points should be taken into consideration : the instructions of food and agriculture organization (FAO) and following the orders of defense concerning wastewater and instructions issued if it is mixed with industrial wastewater .
  • In the case of linking industrial wastewater with the public sewerage network affiliated with water authority , it shall be compatible to the instructions of sewerage network linking and their amendments .

 

Standard stipulations 


In industrial wastewater , the following standard stipulations mentioned in the attached table must be provided according to the final use . The adopted results shall be based on:

  • Samples should be representative and composite according to the flow quantity over the period of the factory's operation ( the number of work hours ) . The numbers of samples  shall not be less than one sample per week for evaluation or water quality study .
  • If the previous clause is not available , the samples shall be taken random according to the quality and continuity of the flow of the outgoing water in a rate that shall not be more than that .
  • Samples shall be taken , kept and analyzed according to what has been mentioned in the book of the standard methods for the examination of water and wastewater issued by the American Society for water research and the American Federal water pollutant monitoring and its amendments or any other methods of analysis if not available in the mentioned reference. 
  • General stipulations and integrated and detailed environmental impact assessment to show the quality of water allowed to get out from the factory in that area especially for non- mentioned properties or specifying rates for them in the attached table .

(+) Unit is milligram / liter unless otherwise is mentioned 
(*) Dissolved oxygen rates are the minimum limit .
(**) This depends on the quality of plants , quantity of production , the irrigation system applied , soil , climate and ground water quality in that area.
(_)  Undetermined : it depends in its determination on standard and general stipulations.
(M) Monthly rate .

Notes on the table:

  • The allowed rate depends on the concentrations of total substances in the water source provided for industry as well as in the aquatic basin affected by this water.
  • The allowed rate depends on the restriction degree - unrestricted , light to  moderate , extremely restricted .
  • The allowed rate depends on the irrigation system followed - drop irrigation , surface irrigation , sprinklers .
  • The allowed rate depends on nitrate concentration in the aquatic basin affected by that.
  • It may reach 2 milligram / liter.
  • The geometric rate depends on
